For heaven's sake, woman. What the hell are you doing? Get down from there immediately!
We have to admit our nerves are in shreds after watching this footage of a devil-may-care Russian skywalker making her way along a beam hundreds of feet above the ground.
The video - which comes to us via LiveLeak - appears to have been shot from a head-mounted camera.
As the fashion-spotters among you will already have noted, the woman's wearing a very nice red top and a good pair of trainers - but WHERE THE HELL IS HER SAFETY EQUIPMENT? (Ahem. Sorry. We've taken some Rescue Remedy now.)
We were particularly shaken at the point where she appears to weigh up whether or not to walk along an even thinner beam.
A word to the wise: don't try this at home, folks!
